maven私服搭建

搭建私服的工具选择

Apache基金会的archiva

http://archiva.apache.org/

JFrog的Artifactory

https://jfrog.com/artifactory/

Sonatype的Nexus

https://my.sonatype.com/
这些都是开源的私服软件，都可以自由使用。用的最多的是第三种Nexus，本文我们主要以这个来讲解，其他2种有兴趣的朋友可以去研究一下。

Windows10中安装Nexus私服
nexus是java开发的，所以运行的时候需要有java环境的支持。

nexus下载和版本

https://www.sonatype.com/nexus-repository-oss

nexus-3.20.1-01-win64

C:Usersjie>java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

nexus启动

nexus.exe /run

exus-3.20.1-01in>nexus.exe /run

浏览器访问

http://localhost:8081/

其他版本可能需要输入：http://localhost:8081/nexus

登录

需要修改密码

Your admin user password is located in
D:chengxu
exus-3.20.1-01-win64sonatype-work
exus3admin.password on the server.

修改启动端口

默认端口是8081，如果和本机有冲突，可以在下面的文件中修改：

${dir}etc
exus-default.properties

nexus仓库类型

上图中是nexus安装好默认自带的仓库列表，主要有3种类型：

代理仓库

宿主仓库

仓库组

ready to connect和manually blocked

需要在仓库中将Block相关的选项去除勾选。
1 Block outbound connections on the repository
2 Auto-block outbound connections on the repository if remote peer is detected as unreachable/unresponsive
等待连接状态不用管，使用的请求下载jar，就会自动变为remote available
